RAZOR-STROP.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed. August 5 1909. Serial No. 511,814.

' strops, such as shown and described in the Letters Patent of theUnited States, No. 580,231, granted to me April 6, 1897.

\ The object of the present invention is to provide a new and lmprovedrazor strop,

more especially designed for accurately stropping thin razor blades, ofthe Gillette and other types, in a very simple and effective manner andwithout much exertion on the part of the operator. For the purposementioned the rocker of the razor strop is adapted to receive aremovable blade holder having retaining means for. holding the razorblade in position.

A practical embodiment of the invention is represented in theaccompanying draw ings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a longitudinal section of the razor strop;.Fig. 2 is a planview of the same withthe leather strop omitted; Fig. 3'is a perspectiveview of the blade holder; and Fig. 4' is an enlarged sectional sideelevation of the rocker, the blade holder in position on the rocker, andthe razor blade in position in the holder.

A slide or casing A is adapted to be moved lengthwise on the stropB ofleather or other suitable material, the strop passing between fixedmembers C and movable members D'arranged in pairs on the ends of theslide .or casing A. The fixed members 0 are in the form of round barsextending transversely across the top of the stro) B, and the movablemembers D are in the orm of fiat plates fulcrumed on transverselyextending pivot pins E, held in the sides of the slide or casing A andprojecting somewhat beyond the said sides, as indicated in Fig. 2, for apurpose hereinafter more fully explained. The free ends of the movablemembers D are pressed on at the under side by springs'F, held on theslide or casing A, so that the strop 13 is clamped between the fixedmembers 0 and the movable members 7 D, with a view to prevent a toorapid forward or backward movement of the slide on the strop B.

In the sides of the slide .or frame A is mounted to rock thetransversely extending shaft G of a rocker or carrier G, and at 1 oneend of the shaft G is secured a pinion H, in mesh with a rack 1, formedor secured on one side J of a shifting frame, having a second side Jconnected by a cross bar J' with the side J, said sides J and J of theshifting frame being provided with elongated slots J engaging theprojecting ends of the pivot pins E previously referred to. The crossbar J is provided with a depending handle K, to be taken hold. of by theoperator for moving the shifting frame forward and backward until themovement thereof is limited by the ends of the slots J 3 abuttingagainst the pins E. a

The rocker or carrier G is provided with a clip G formed from a singlepiece of sheet metal bent around the shaft G and secured thereto bysolder or other means.

The clip G is rovided with two spaced members G receiving between them ablade holder L, for carrying the razor blade N. The blade holder L isformed from a single piece of sheet metal, doubled up to form at thedoubled-up end a handle L and to provide two spaced members L and L forreceiving between them the razor blade N, as plainly indicated in thedrawings.

The member L is provided with inwardly struck up lugs L registering withapertures L formed in the other member L it being understood that therazor blade N is provided withapertures adapted to engage the lugs Lwhen inserted between the members L and L of the blade holder L. Themembers L and L are also provided at their outer faces withlongitudinally extending ribs L, adapted to engage correspondinglyshaped grooves G formed on the inner faces of the members G of the clipG of the rocker G.

In using the strop, the blade N is placed between the members L and L ofthe blade holder L at the time the said members are spread apart, andwhen the blade is in position in the holder L, then the operator lacesthe holder L with its two members L and L firmly pressed to ether,between the members G of the cli Lt, by inserting the holder L from thaten of the rocker opposite the one having the pinion H, as will bereadily understood by reference to Fig. 2.

' locked to the slide to permit the latter to l Now, by having the ribsL engaging the grooves G, it is evident that the blade holder L isalways held in the same posi tion in the rocker and as the blade N iscorrectl'y held in the holder L, it 1s evident that the-outer cuttingedge of the blade N stands at the proper angle relatively to the upperface of the strop 'B when the machine is used for stropping the blade N.When the blade holder L carrying the blade N is in position in therocker G and one end of the strop B is hung up on 'a fixed support andthe other end is taken hold of with one hand by the operator, then thelatter takes holdwith his other hand of the handle K and moves the slideor casing A' lengthwise on the strop B, whereby the rocker G is causedto rock to bring the opposite sides ofthe cutting edge'of the blade Nalternately into contact with the upper or strap in face of the strop Bto strop the razor la e. After the razor blade N is stropped, theoperator takes hold of the handle L of the blade holder L and pulls thesame out of the cli G. The members L, L of the removed lade holderreadily open by their own resiliency, to allow convenient removal of therazor blade N for use in the safety razor.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A razor strop, comprising a strop, a slide fitted to move lengthwise,on the strop, said slide having spring pressed means for increasin theresistance of the slide on the strop an provided with"pro ections on itssides, a blade carrier mounted to rock on the slide and having a inionat one end, and a shifting frame on t e slide, and having a rack meshingwith the pinion on the blade carrier, said rojections of the slide,whereby the shifting rame can be first'moved independently of the slideto rock the blade carrier and then be moved along the strop.

2. A razor strop comprising a strop, a l

rame being provided with a handle and slots in its sides receiving theslide fitted to move lengthwise on the strop, said slide having fixedand yielding members at its end between which the strop passes, a bladecarrier mounted to rock on the slide and having a pinion at one end,

anda frame fprovided with a rack engaging whicha strop is adapted topass, and rovided with projections on its sides, a b ade carrier mountedto rock on the casing and having a pinion at one end, and a shiftingframe having on its upper edge a rack engagin the pinion of the bladecarrier and provi ed in its sides with slots receiving the rojections ofthe casing and with a han le on its under side.

plns, a rack on one of the said frame sides,

a handle on the connecting bar of the shifting frame a rocker mounted onthe said slide, a pinion on the said rocker 111 mesh with the said rack,and a blade holder for removable engagement with the said rocker.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
